Assassination 6

After speaking with the Fixer, it's time to go on this rather elementary assassination mission. What makes this mission even remotely difficult isn't the fact that your targets are mobile or attempt to get away. Rather, it's that there are simply a lot of enemies that need to be dealt with. Thankfully, as long as you have a sniper rifle in your arsenal (and you certainly should), you're in the clear. So, from where you talk to the Fixer on the payphone, head southward to the industrial island at the southern end of Alderney. It's in one of the industrial complexes south of Muskteer Avenue along the water's edge that the action is going to go down.

Once you arrive near the complex, you're going to have to bust through the chain link fence (preferably with your car) and take a heightened position along one of the many catwalks in front of the enemy positions (marked as red dots on your HUD). As long as you don't wildly open fire on them as you're positioning yourself, or otherwise get too close to them, you should be just fine in completing this mission covertly... at least initially. Use your sniper rifle's scope to hone in on enemies, shooting them in the head after locating them with sight and some HUD direction. The enemies will begin to scramble, but you should certainly be able to thin their numbers out considerably before they make it to the ground floor. Their incessant gunfire and constant movement (not to mention the red dots on your HUD) will give away their positions adequately. When the last one is slain, this assassination mission comes to an end.
